EXCLUSIVE 'How I Met Your Mother' Clip: Making Of 'Subway Wars'

In honor of today's release of 'How I Met Your Mother: The Complete Sixth Season' on DVD and Blu-ray, AOL TV has an exclusive clip from one of the set's extra features.

In the 'Subway Wars' episode, the gang raced from the Upper West Side to Tribeca (for you non-New Yorkers, that's a short distance, mile-wise, but a long distance when you're in a city crowded with 8 million people) using their preferred method of transportation: Lily took the subway, Ted took the bus, Marshall ran, Robin hailed a cab and Barney ... ate a steak, faked a heart attack and cruised in an ambulance.

Check out the clip below for a behind-the-scenes look at Neil Patrick Harris filming the episode, plus his thoughts on why Barney's way downtown was the best.
